ATTORNEY United States Patent 2,731,719 KNIFE HANDLE CONSTRUCTIONApplication June 8, 1951, Serial No. 238,493 1 Claim. (Cl. 311-164) Thepresent invention relates to knife constructions, and has particularreference to a novel assembly for knife handles.

The principal object of the invention is to provide an assembly wherebythe bolsters and the ornamental cover plates are firmly secured to theknife body.

Another object of the invention is to provide a novel bolsterconstruction which is attached to the liner plate and receives theornamental cover plate.

Another object is to provide a novel assembly which locks both thebolster plate and the cover plate to the liner plate.

With the above and other objects and advantageous features in view, theinvention consists of a novel arrangement of parts more fully disclosedin the detailed description following, in conjunction with theaccompanying drawings, and more specifically defined in the claimappended thereto.

In the drawings,

Fig. 1 is an elevation of a knife, partly opened, and showing thebolsters and cover plates as locked to the knife body;

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1, showing one bolster, the cover plateand the other bolster being removed;

Fig. 4 is a perspective front view of the novel bolster;

Fig. 5 is a perspective rear view of the novel bolster; and

Fig. 6 is the rear view of the cover plate.

It is my purpose to provide a simple arrangement for securing bolstersand cover plates to the liner plates To this end, I stamp sheet metalbolsters shaped to receive the ends of an ornamental cover plate,

liner plates. This assembly is quick and accurate, and is readilyaccomplished by unskilled workers.

Referring to the drawing, the assembled knife 10 includes a body 11having knife blades 12 which are pivotally mounted therein in the usualmanner, bolsters 13 and ornamental cover plates 14. Each bolster 13includes a dome shaped cap portion 15, see Figs. 3, 4 and 5, a reducedouter end 16 having a hook lug 17, and a linear downward extending innerwall 18 of narrow width, which has an elongated extension 19 extendingfrom the lower edge thereof, the extension 19 having a rivet opening 20and a downward extending snap tab 21 with a vertical face which isslightly curved inwardly at its extremity.

The bolsters are mounted on the liner plates 22 of the knife body 11 byseating the end hook lug 17 over the outer edge of the liner plate,which has a raised portion 23 for this purpose, and snapping the innersnap tab 20 over the linear edge 24 of a half-moon piercing 25 in theliner plate, whereby the bolsters seat on the liner plates in properposition to receive the ornamental cover plates therebetween.

As illustrated in Fig. 2, the cover plates 14 are positioned between theinner walls 18 of the bolsters on each side of the knife body, eachcover plate being 2,731,719 Patented Jan. 24, 1956 provided with twospaced mounting fingers 29 at one end thereof, which seat into the endopenings 30, see Fig. 5, and extend into the hollow dome of the bolsterplate with the bolster plate end wall therebetween. The cover plate hastwo recesses or grooves 31, in its lower surface, to seat snugly overthe bolster elongated extensions 19, each cover plate having rivetopenings 26 aligned with the bolster elongated extension openings 20,whereby rivets 27 pass through cover plate rivet openings 26, thebolster elongated extension openings 20, and aligned rivet openings 28in the liner plate, and are headed over to lock the parts in assembledrelation. The recesses and the extensions cooperate to prevent lateraldisplacement of the parts.

The improved construction thus includes novel bolster plates which snapseat to the liner plates and cover plates which engage one bolster plateto be held in position, the cover plates, bolster plates and linerplates having aligned rivet receiving openings whereby locking togetherof the parts is quickly effected.

Although the cover plate is illustrated as having mounting fingers atone end, it may be desirable for certain knife constructions to havemounting fingers at both ends, in which case the mounting fingers at oneend are inserted in the contiguous bolster openings, and the otherbolster is snap seated over the other cover plate end. This makes a veryfirm anchorage for the cover plate, supplementing the coaction of thecover plate recesses and the bolster extensions, and locking effect ofthe rivets.

Although I have described a specific construction embodiment of theinvention, it is obvious that changes in the size and shape of the partsmay be made to suit the requirements for different types of kniveswithout departing from the spirit and the scope of the invention asdefined in the appended claim.

I claim:

In a knife construction, a knife body having upper and lower linerplates, bolsters at each end of the liner plates, and cover plates overthe liner plates and intermediate the bolsters, each liner plate endhaving a raised portion, a piercing, and a rivet opening intermediatethe raised end portion and the piercing, each bolster having a domeshaped cap terminating in a hook lug at its outer end adapted to seatbeneath the associated liner plate end, and having a narrow extensionfrom its inner end extending downwardly and then outwardly over theliner plate, said extension having a rivet opening in alignment with theassociated liner plate rivet opening and a terminal snap tab adapted tosnap seat in the associated liner plate piercing, each cover platehaving a longitudinal groove at each end adapted to seat over theassociated narrow bolster extension and a rivet opening aligned with thebolster extension and liner plate rivet openings, each cover platehaving spacing mounting fingers on at least one end thereof adapted toreceive the downwardly extending portion of the associated bolstertension therebetween and to seat within the bolster dome, and rivetsextending through the aligned linear plate, bolster extension, and coverplate rivet openings.
